util/amdfwtool: Add option for directory location 

The AMD firmware directory can go in a number of different locations.
This patch allows amdfwtool to write the directory correctly for those
different locations.

If the --location switch is not added to the command line, the default
location at ROM base address + 0x20000 is used as before.

BUG=b:65484600
TEST=Set PSP firmware location, compare amdfw.rom to previously built
version.  Verify new location pointers.
